Frequently Asked Questions - TH810T Cotech

How do I switch the thermostat from frost guard to heat guard mode?

To change the function, press and hold the [⏻] button, then press [▲] for 3 seconds several times until the desired mode is displayed: frost guard (⬆) or heat guard ().

How can I adjust the activation temperature?

Use the arrow buttons [▲] and [▼] to set the desired activation temperature within the range of 5°C to 30°C.

What do the indicator lamp colors mean?

When the thermostat is on: red lamp means the socket is off (temperature not reached), green lamp means the socket is on (temperature reached). If the lamp is off, the thermostat is turned off via the power switch.

What does 'LO' on the display indicate?

'LO' indicates that the built-in rechargeable battery is low. Plug the thermostat into a wall socket and let it recharge for at least 10 hours.

How do I reset the thermostat to factory settings?

Press the [Reset] button. The thermostat will revert to the default frost guard mode with an activation temperature of +5°C.

Can this thermostat be used to control a cooling unit (air conditioner)?

Yes. Switch the function to heat guard mode (activation on rising temperature) by pressing [⏻] and [▲] simultaneously for 3 seconds. Then set the desired activation temperature.

What is the default activation temperature when the thermostat is new?

The factory default is frost guard mode with an activation temperature of +5°C.

How long does it take for the thermostat to react to a temperature change?

The thermostat has a built-in delay to compensate for normal temperature variations. It can take between 1 to 3 minutes to react to a temperature change.

What should I do if the display shows nothing?

Plug the thermostat into a wall socket and let it recharge for at least 10 hours. If the problem persists, press [Reset].

Is the thermostat waterproof or suitable for outdoor use?

No, the thermostat is intended for indoor use only. It should not be exposed to moisture or outdoor conditions.

1. Description

• This thermostat is designed to be used indoors either as a frost guard (to prevent frost damage) or to regulate air conditioning units and prevent the temperature from becoming too high.
• Simple to use – preset as a frost guard set to activate at +5 °C. Only needs to be reprogrammed if it is to be used to regulate an air conditioning unit or if you wish to alter the activation temperature.
  • Max power 18-2168: 2990 W, 13 A (36-1181: 3680 W, 16 A).

• Easy to change function and activation temperature.
  • Measuring range: 5–30 °C.

• Indicator lamp function:

• Not on: The thermostat is turned off at the power switch.

• Shines red: The temperature has not reached the activation temperature and the socket on the thermostat is turned off.

• Shines green: The temperature has reached the activation temperature and the socket on the thermostat is turned on.

• Ambient temperature (23.8 °C in picture).

• ◆ This symbol is displayed* if the thermostat is set to activate when the temperature drops (frost guard).

• ✿ This symbol is displayed* if the thermostat is set to activate when the temperature rises (heat guard).

• The set activation temperature is also displayed (+5 °C is preset at the factory).

• [Reset] Press this button to reset to the factory default settings.

• [▼] Lower the activation temperature.

• [▲] Raise the activation temperature.

• [On/off switch: Turn the thermostat on/off.

*Note! The symbol is only displayed when the temperature has reached the set activation temperature or if you turn the thermostat off using its on/off switch [5] (remember to turn the thermostat back on again!).

2. An example of use

Situation: The plug-in thermostat is to be used as a frost guard and switch on an electric radiator in a room when the ambient temperature falls below +5 °C.

1. Plug the thermostat into a wall socket.
2. Plug the electric radiator into the socket on the thermostat and make sure that the electric radiator is switched on.

3. The display shows the current ambient temperature in ^ C and the set activation temperature (factory preset to +5 ^ C). The plug-in thermostat will now control the on/off switching of the electric radiator.

4. As long as the temperature is normal, the indicator lamp (1) will be red and the electric radiator will not be switched on.

5. If the ambient temperature drops below +5 °C, the plug-in thermostat will activate and turn the electric radiator on.
6. ♂ (3) will be displayed and the green indicator lamp (1) will come on for as long as the electric radiator is switched on.

3. Function

• The plug-in thermostat is designed to be used indoors to control the on/off switching of heating/cooling appliances in case of rising/falling ambient temperature.
• When sold, the plug-in thermostat is set to work as a frost guard and activate when the ambient temperature falls below +5 °C. If you wish to alter the activation temperature (or use the thermostat to activate a cooling unit) the setting must be changed.
• Press the arrow buttons [▲] and [▼] simultaneously to change the display units from °C to °F.

Indicator lamp function

• Not on: The thermostat is turned off at the power switch.
• Shines red: The temperature has not reached the activation temperature and the socket on the plug-in thermostat is turned off.
• Shines green: The temperature has reached the activation temperature and the socket on the plug-in thermostat is turned on.

Frost guard mode

If the activation temperature is set to +5 °C and the ambient temperature falls, the plug-in thermostat will activate when the ambient temperature has fallen below and been below +5 °C for at least ten seconds (the temperature might fall even lower before the thermostat activates).

The plug-in thermostat will be activated until the ambient temperature has risen one degree from when it was activated and has been so for at least ten seconds.

This means that the displayed temperature is not always the same as the activation temperature.

Note! The plug-in thermostat has a built-in temperature margin in order to compensate for normal variations in temperatures such as when a door or window is opened. It can take between 1 and 3 minutes for the plug-in thermostat to react to a temperature change.

Note!

• You, the user, bear full responsibility for ensuring that nothing freezes.
  • The plug-in thermostat will not work during power cuts or if a fuse has blown.
• The amount of heat needed to prevent freezing depends on a number of factors such as the size of the room, outdoor temperature, etc.
• The operation of the plug-in thermostat and the temperature of the room should be checked regularly.
• The operation of the plug-in thermostat also depends on its placement: high/low, position in the room, etc.
